v AIR CLEANER FOR CARBURETORS.

Application led July 12, 1924.' Serial No, 725,702. i

To' all' whom t may concern.' y

Be it known that I, FREDERICK Sfrim'rfrivnn OREM, a citizen of the UnitedStates, and a residentof Baltimore, in the county of 5 Baltimore and State of Maryland, have in vented certain new and useful" Improvements in Air. Cleaners `for Carburetors, of which the following is a specification.

The invention concerns means to furnish clean air to carburetors and it consists in the features and combination and 'arrange ment of parts hereinafter described and particularly pointed out in the claim.

The dran-'ing represents an elevation of 15 the apparatus partly in sect-ion.

' In this drawing 1 indicates conventionally a carburetor having a-supply pipe 2 load,- ing thereto froml an air cleaner device 3. This air cleaner may be of any suitable form, such, for example, as that shown in Letters Patent of the United States granted- In lthe operation of the apparatusftlie cleaner 3 is constructed to supply clean air 35 -to the pipe 2 for the ordinaryoperation of the lcarburetor of the automobile, or other situations in which the carburetor maybe used. If, however, the demand of the carburetor for air under the suction of the en- ,40 gine increases beyond that for which the4 cleaner 3v is calculated, and therefore the pressure ofair in the pipe 2 becomes reduced, the valve 8 will automatically open and bring' the supplemental' cleaner 4 into 45 service, for supplying the deficiency in airv pressure under the demand of the carburetor. Normally, however, thevalve`8 will air cleaner, a pipe connectingr the main air cleaner with the supplemental air cleaner in spaced apart relation, and a valve for bringing said supplemental cleaner into service automatically when the main cleaner 60 is out of service. v

In testimony whereof, I allix my signature.
